Retina Ready Background Mixin with Compass

	// 1.- This mixin works when you add class retina by JavaScript to html tag or when you use media queries
	// 2.- This solution works with the sprites of http://compass-style.org/
	// 3.- If your retina sprite have a diferente size with your regular sprite you can set the image with the folowing mixin:

	$icons-retina: sprite-map("icons-retina/*.png");

	@mixin background-retina($file-name) {
	background: $icons-retina;
	$ypos: round(nth(sprite-position($icons-retina, $file-name), 2) / 2);
	background-position: 0 $ypos;
